CORNER STUDDING FOR PLASTER-BQARD WALLS.

Application led March 25, 1924. Serial No. 761,681.

This invention relates to fireproof building wall constructions and moreparticularly to metal corner studding for plaster board walls.

An important object of my invention is to provide a simple and efficientmetallic die formed supporting` stud for fireproof plaster' boardbuilding walls at their corners, that may be readily erected in positionand which is provided with means for effectively preventing injury totheir corners after plaster has been applied thereto.

Another object is to provide a metallic corner stud for plaster boardwalls in which the boards may be. readily secured thereto withoutemploying nails or other similar securing means. i

In the accompanying drawings l have illustrated a. preferred embodimentof my invention, it being understood however, that no limitation isnecessarily made to the precise structural details therein exhibited,but various changes, alterations and modifications may be resorted towithin the scope of my invention when desired.

Fig. 1 is a fragmentary perspective view of my studding showing thecorner edges of the plaster board of a building wall held securedtogether.

Fig. 2 is an elevation of my studding looking at one inner edge thereof.

Fig.' 3 is an elevation of my studding looking at the other inner edgethereof.v

Fig. /1 is a horizontal section of my studding taken on line 1 -1 ofFig. 2.

My studding includes two Istamped metal angle bars, namely an outerangle bar 1 and an inner angle bar 2. The bar 1 is stamped from a sheetof metal which is bent at 3 upon itself, forming a corner bead 1, andbent from the base of said bead at angles of 15 degrees forming anglemembers 5 and 6 extending` at right angles to each other, the member 6being of greater width than the member 5. Member 5 is provided with aplurality of superimposed plaster key openings 7, and member 6 isprovided with a plurality of superimposed plaster key openings 8. Bar 2is stamped from a sheet of metal in the form of two angle members 9 and10 extending at right angles to each other. Bar 2 is placed inside bar 1with its -inside facing outwardly and its member 9 against the inside ofmember 6 of bar 1, and with the edges ofthe members 6 and 9 coinciding,so that the member 10 of bar 2 is spaced inwardly from member 5 of bar 1at a distance sutlicient to permit the corner edge of a sheet of plasterboard 11 of one wall of a tireproof building to lit between saidmembers. Members 6 and 9 are spot welded together at their edges atsuitable distances apart as indicated at 12. lrongs 13 are formed on theedge of member 1() of angle bar 2 at suitable intervals apart, whichprongs are bent over the corner edges against the inner side of a sheetof plaster board 111 of the other wall of a iireproof building, theangle bar 2 forming a seat for the corner edge of the plaster board ofthe said other wall.

The lower end of the studding `may be mounted in a recess in theconcrete door and the upper end 0f the studding may be mounted in arecess of the ceiling of a iireproof buildimT for securing the studdingin position in the building.

Plaster 15 is spread over the outside of the plaster board 11, member 5of the angle bar 1, and the adjoining side of bead 41 of if a. thicknesscoinciding with the outer edge of the bead, the plaster filling theopenings 7 against the plaster' board in the form of keys. Plaster 16 isspread over the outside of the plaster board 11,`member 6 ofangle bar 1and the adjacent vside of the bead 1 of a thickness coinciding with theouter edge of the bead, the plaster filling the openings 8 against theplaster board 11 in the form of keys. Plaster 17 is placed on the innerside of the plaster board 11 and plaster 18 is placed against the innerface of plaster board 141, covering the prongs 13.

The outer edge of the bead 1 receives all impacts against the corner ofthe wall and protects the sam-e.

What l claim 1. A metallic corner studding comprising an outer anglebar, an inner angle bar placed with one of its members against theinside of one of the members of the outer angle bar, means for securingsaid members together providing a space betweenthe other members of saidangle bars to receive the corner edge of the plaster board of one wall,the

corner edge of the plaster board of the other wall resting in the innerangle bar, and

means for .securing the latter plaster board in said inner angle bar.

2. A metallic corner studding comprising an outer angle bar, an innerangle bar placed with one of its members against the inside of fifi oneof the members of the other angle bar, means for securing said memberstogether providing a space between the other members of said angle barsto receive the corner edge of the plaster board of one Wall, the corneredge 0l the plaster board Of the other Wall rest-ing in the inner anglebar, and prongs on the edge of the spaced member of the inner angle baradapted to be bent over the inner edge ot the latter plaster board.

3. A metallic studding Comprising an outer angle bar formed with anexternal bead at its corner, an inner angle bar placed with one of itsmembers against the. inside oi one of the members of the outer anglebar, means for securing said members together, providing a space betweenthe other members of the angle bars to receive the corner edge of theplaster board of one wall, the corner edge ot' the plaster board of theother Wall resting in the inner angle bar, and means ior securing thelatter plaster board in said inner angle bar.

4L. A metallic corner studding an outer angle bar.y an inner angle barplaced with one vof its members against the' Ainside of one of themembers of the outer angle Comprising bar and said members being spotWelded together, in sueh position as to provide a space between theother members oit' said angle bars to receive a corner edge of theplaster' board ot' one Wall, the corner edge of the plaster board of theother Wall resting in said inner angle bari and means for securing` thelatter plaster beard in said inner angle bar.

5. A metallic corner studding comprising an outer angle bar, an innerangle bar placed with one of its members against the inside oi one otthe members of the outer angle bar, means for seeming .said memberstogether providing a space between the other mem bers of said angle barsto receive the corner edge et' the plaster board oi one wall, the eorneredge or the plaster board of the other wall resting in the inner anglebar, and means for securing the latter plaster board in .said innerangle bar, the members of the enter angle bar being provided Withplaster :ey openings.

In Witness that l Claim the foregoing l have hereunto subscribed my namethis 5th day of March, 1924.
